I just pulled the trigger and updated from 1239 too 1240 it didn't even download any data it took less than a second so I guess it's just a version number bump so everyone is on the same version number

2. A high-speed internet connection of at least 20Mbit/s for 2560 pixel Ultra HD or 40Mbit/s for the full 3840 pixel Ultra HD experience. It's recommended that a wired connection from the TV to the home router is used for the most consistent performance.

To start watching the live stream in Ultra HD, either:

• Press the Red Button while watching the BBC's coverage on BBC One or BBC Two• Open the BBC iPlayer app on your connected TV. The Ultra HD stream will be available from the BBC iPlayer home screen as soon as programme coverage begins.

As with previous live Ultra HD trials, there's a limited number of spaces for each match with the stream available to tens of thousands of people on a first come, first served basis. So join the trial early for the best seats on the court.

Thanks again for your interest, we will be in touch again the next time a UHD programme becomes available.

I tried the HLG/UHD Wimbledon service last year and it was pretty impressive, though confined to centre court and it was fine for me on a wireless connection via a TV fairly close to the router. Usuallly i did not have much trouble accessing the service, though possibly more folk will be aware this time. In the meantime my Broadband has been upgraded from Fibre to Fibre Max, so will be interesting to see if that makes a difference.

The only thing is that the stream is slightly behind live play on the braodcasting channel, though this applies to these types of services whether HD or UHD.
